Value Collection BD-34902-1 Grade 8 Alloy Steel Dowel Pin

Product Description

The VALUE COLLECTION BD-34902-1 is a Grade 8 alloy steel standard dowel pin designed for precision alignment and fastening applications in mechanical assemblies. The pin measures 3/8 inch in diameter and 1-1/4 inches in length, with a diameter tolerance of 0.0002 inches for tight, reliable fits. It carries a Rockwell hardness rating of C 50-58 and a double-shear breaking strength of 28,700 pounds, making it a dependable choice where shear resistance and positional accuracy matter. One end is beveled and one end is rounded to aid insertion and seating during assembly. Machinists, millwrights, and maintenance technicians are the primary installers of this hardware.

This dowel pin is suited for use in jigs, fixtures, dies, and machine components where repeatable alignment between mated parts is required. The Grade 8 alloy steel construction makes it appropriate for high-load industrial environments. It is commonly installed in press-fit or slip-fit bores in manufacturing, tooling, and equipment maintenance contexts. The package quantity is 25 pins, with a minimum order quantity of 1.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an arbor press or mallet with a driver of appropriate diameter. Confirm bore diameter and tolerance before installation to ensure the correct fit class. Always deburr and clean the receiving bore before pressing the pin into place. Follow applicable workplace safety procedures and equipment lockout/tagout protocols before performing maintenance involving pinned assemblies.
